Infertility surgery is dead: only the obituary remains?
Fertility and sterility ·doi:10.1016/j.fertnstert.2007.02.041

Despite the multiple advantages of assisted reproductive technology compared with surgery, there remain several diagnoses for which surgery is still widely performed: distal tubal occlusion, regret of permanent sterilization, and endometrio…
